He was found guilty of one count of recklessly infecting a partner with HIV, one count of attempting to recklessly infect a partner with HIV, and three counts of recklessly exposing partners to HIV.

Under Missouri state law, it is an offence to fail to disclose your HIV status to a sexual partner – but Johnson’s partner Dylan King Lemons became concerned after finding Johnson on gay hook-up apps.

Johnson testified that he had informed all six men about his HIV status – but now faces at least 30 years in prison for failing to disclose the information, reports KMOV.

Judge Jon Cunningham, who issued the sentence, told Johnson he had committed “very severe” crimes. Prosecutors said he didn’t tell the partners he had HIV. “The main thing is the profound effect your actions have had on the victims and their families,” the judge said.

Many states have laws that make it a crime to fail to disclose your HIV status, even if sex is protected or viral load is undetectable.

The laws are controversial, with some HIV campaigners calling for a more nuanced system.

Kenyon Farrow, of the Treatment Action Group, has said of the case: “Throwing people in jail is probably the worst thing you can do if you want to encourage people to feel comfortable enough to get tested for HIV, receive treatment and openly discuss their status.

“If people are so concerned with HIV transmission, then perhaps the Missouri legislature and Governor Nixon should start by repealing this law, and expanding Medicaid to ensure everyone with and at risk for HIV, has access to appropriate services and healthcare.”
